Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

An embodiment of an electrochromic glass dimming window assembly as shown in fig. 1 to 2 includes electrochromic glass 1 and third tempered glass 3, the electrochromic glass 1 and the third tempered glass 3 are oppositely arranged, a hollow layer 2 for heat insulation and sound insulation is formed between the electrochromic glass 1 and the third tempered glass 3, and the edge of the electrochromic glass 1 and the edge of the third tempered glass 3 are connected through a glue package 4. The hollow layer 2 is a 9A hollow layer. Electrochromic glass 1, hollow layer 2 and the third toughened glass 3 of 6mm thick pass through gluey encapsulation piece 4 and make up into the hollow glass that discolours, install in window frame or casement structure 5 again, install window five metals 6.

The electrochromic glass 1 is composed of a central layer and three layers having symmetry on both sides. The electrochromic glass 1 includes a first tempered glass 11, a first transparent conductive layer 12 provided on the first tempered glass 11, a first tungsten trioxide electrochromic layer 13 provided on the first transparent conductive layer 12, an electrolyte layer 14 provided on the first tungsten trioxide electrochromic layer 13, a second tungsten trioxide electrochromic layer 15 provided on the electrolyte layer 14, a second tempered glass layer 17 provided on a second transparent conductive layer 16 provided on the second tungsten trioxide electrochromic layer 15, and a second transparent conductive layer 16. The second tempered glass layer 17 is located adjacent to the third tempered glass 3.

The first tempered glass 11 was 5mm thick tempered glass. The second tempered glass layer 17 is 3mm thick tempered glass. The first transparent conductive layer 12 and the second transparent conductive layer 16 are ITO transparent conductive layers coated with graphene. The first transparent conductive layer 12 and the second transparent conductive layer 15 are respectively led out of a connecting terminal 18 coated with graphene. By adopting the connecting terminal 18 structure coated with graphene, the graphene improves the conductivity, overcomes the technical defect of insufficient driving voltage in the middle of large-area electrochromic glass in the prior art, and has the advantages of rapid color change, high stability and reliability and uniformity.

As a further explanation of this example, the working principle of electrochromic glazing is now explained: according to the oxidation-reduction reaction of the oxide, the inorganic tungsten oxide color-changing film is coated, the ITO transparent conducting layer and the wiring terminal 18 are connected with a wire, and the power supply is switched on to realize control. The active layer based on tungsten oxide is in a nearly transparent discolored state before the energization reaction, and when a voltage is applied, hydrogen ions from the ion storage discoloring layer and electrons from the electrode (the electrons actually come from the storage layer but pass through the electrode) are obtained, and tungsten oxide is reduced to produce tungsten bronze (HWO3) and turns blue. (tungsten oxide is reduced, and more specifically the +6 tungsten ion is reduced to +5 because of the resulting electron.) when a reverse voltage is applied to the glass in the blue state, the electrons and hydrogen ions are extracted from the tungsten bronze and return to the ion storage coloration layer through the original paths (i.e., the electrons pass through the external circuit and the ions pass through the intermediate electrolyte layer). Thus, the blue tungsten bronze changed back to transparent tungsten oxide, completing a color change cycle. The shading coefficient and the light transmittance of the glass are controlled by changing the current through adjusting the size change of the resistor, so that the effects of shading and energy saving are realized. The reaction product involved in this example, either tungsten oxide or tungsten bronze, had good stability. This is a very attractive feature of electrochromism, and its color state can be maintained without applying a continuous voltage, so that the energy can be saved. This also makes it competitive with respect to two other color-changing techniques requiring a sustaining voltage, the suspended particle technique and the polymer dispersed liquid crystal technique.

This embodiment can be used for building intelligent curtain wall window, and the window need not install curtain, tripe or light screen additional, and can be through adjustment button or cell-phone APP, the colour depth, the shading coefficient of convenient regulation window. The electrochromic glass has wide application, and can also be used for military camouflage equipment, airplane cabin windows, automobile intelligent glass, intelligent mobile phones, intelligent televisions and the like.

The electrochromic glass in the embodiment is novel functional glass and has the characteristics of environmental protection, energy conservation and high efficiency which are ultimate targets of development of the glass industry. The electrochromic material is an intelligent material, is a strategic emerging industry in our country, is a fourth generation material following natural materials, synthetic high polymer materials and artificially designed materials, is one of important directions of the development of modern high-technology new materials, supports the development of future high technology, gradually eliminates the boundary between functional materials and structural materials in the traditional meaning, and realizes structural functionalization and functional diversification.

Other structures of this embodiment are seen in the prior art.
